GK3: Compact powerhouse with 50% more capacity
The GK3 is a 3-row trailed top lifting harvester that delivers up to 50% more capacity than a conventional 2-row machine working at 3.3 m width — all while keeping its transport width under 3 metres. Its compact design and rotatable elevator make the GK3 easy to transport by road, backed by full EU type approval.
Gentle harvesting, straight into boxes
The GK3 is designed for growers who want to unload directly into boxes during harvesting. With intuitive cleaning controls and no hedgehog belt, the right amount of soil can be transported with the product — ideal for box filling.
Purpose-built top lifting elements
This harvester features 14-metre-long super-grip harvesting belts with individual Floating Shares. These unique harvesting elements offer maximum stability and precision — even at higher driving speeds. An automatic depth control system ensures accurate ridge following. Thanks to the dual auto-steering (DAS), the machine is capable of following any drilling pattern with ease.
Patented cutter set for fast, crop-friendly cutting
The GK3 comes with a patented cutter set first introduced on the second-generation ZK4. This innovation enables high-speed cutting with excellent crop protection. The knives are made from wear-resistant material and can be reversed — doubling their lifespan. A maintenance-free gearbox and single motor drive system offer reliable performance with minimal wear.
Efficient elevator with active sidewalls
Product is transferred via a 90 cm cross conveyor to the 120 cm elevator with active sidewalls to avoid damage. Optional rubber pins can be added to further boost capacity. Thanks to optimal product distribution, the GK3 is ideally suited for harvesting into boxes — without compromising output.
User-friendly controls and compact transport
The ISOBUS interface — compatible with a 12” colour touchscreen — offers a user-friendly experience. The extendable rear axle and standard integrated wheel drive ensure maximum stability and traction in all conditions. With a transport width of just 3 metres, the GK3 remains easy to move from field to field.
